14.1

14.2 Prior to firing, check that the electrical supply to
the boiler is 'On' (The green boiler ‘Stand by’ indicator
will light) and the gas service cock is in the open
position.

Set the boiler's central heating and domestic hot
water temperature controls to maximum by
turning them fully clockwise.

Set the external room thermostat (if fitted) to
maximum and open the thermostatic radiator
valves to maximum.

14.3 Switch the boilers function switch to the central
heating and domestic hot water position. The boiler's
control unit will now automatically carry out pre-
ignition safety checks before igniting the burner.

14.4 During the 10 second burner ignition attempt
visually check that all of the burner blades ignite
correctly.
If necessary, adjustments to the ignition rate may
be made using potentiometer P4. Turning P4
clockwise increases the ignition rate and anti-
clockwise decreases the rate. After successful
ignition check the integrity of the boiler's flue for
tightness and correct operation.

14.5 Check the boiler for correct domestic hot water
operation by opening and closing the household
domestic hot water draw off taps.

14.6 In order to maintain the appliance warranty after
initial filling the heating system must be thoroughly
flushed using a propriety cleanser to remove foreign
material and contaminants.

14.7 Restart the boiler and again allow the central
heating

system

to

reach

maximum

operating

temperature. Check that all the water connections
throughout the system are sound and bleed each of the
heating systems radiators and purpose made air release
points in turn.

14.8 Check the system pressure and top up if necessary.

14.9 Reset the central heating & domestic hot water
temperature controls and room thermostat to the
desired temperature settings.

15.1 The boiler incorporates 4 potentiometers and a
bank of dip switches to allow adjustment to its pre-set
parameters. These are situated on the rear of the
control panel.

The potentiometers can easily be accessed by removing
the cover on the rear of control panel

(Figure 19).

(Figure 20).

However

, to reach the dip switches, the control panel

must be opened.

15.2 Setting the maximum c/heating flow temperature:
The boiler is dispatched with a maximum flow
temperature factory set to 90°C. Where a lower
maximum temperature is required such as in the case of
under-floor heating, the factory setting can be altered
between a maximum of 50°C and a minimum of 30ºC, by
fitting dip switch '6' into ON position.

Important Note.
In order to maintain the appliance’s warranty and
so as to comply with the Domestic Heating
Compliance Guide; when the boiler is to be
installed to an existing central heating system,
the system must be properly cleansed using a
proprietary cleanser before the boiler is
connected to the system. On all installations,
after connecting the boiler to the system and
initially filling with water, a proprietary inhibitor
must be added to the system water to prevent
corrosion.

14. Commissioning

Important Notice

Failure to thoroughly power flush the heating
system with the boiler disconnected or to add an
anti corrosion inhibitor to the system water will
invalidate the boiler's warranty.

The condensate trap must be filled with water and
plastic discharge pipe connected to drain before
operating the boiler.

        The  Capriz  25 & 28  boilers  have  been  tested
and  pre-set  at  the  factory  and  is  dispatched with its
on  board  controls  set  to provide a maximum central
heating  and  D.H.W.  output.  Consequently,  once  all
the  connections  have  been  made  and  the boiler has
been  filled  with  water  to  the  desingned  system
operating  pressure, the  boiler  may  be  fired prior to
adjusting  it’s on  board  parameters  to  match  the
heating  systems  requirements.
